COORDINATION OF THE SHARING OF SOURCE CODE IN MEDIUMETO LARGE-SCALE SOFTWARE DEVELOPMENT PROJECTS POSES A DIFFICULT PROBLEM IN THE ABSENCE OF A SOURCE CODE LIBRARIAN SYSTEM. UNFORTUNATELY, SYSTEMS OF THIS TYPE, WHILE POWERFUL AND FLEXIBLE, GENERALLY REQUIRE A LEVEL OF EXPERTISE AND COMMITMENT NOT COMMONLY FOUND IN THE APPLICATIONS CODE DEVELOPER. IN AN ATTEMPT TO ADDRESS THIS PROBLEM, THIS PROPOSA ...

TWO MECHANISMS ARE IDENTIFIED BY WHICH AN ELECTRICALLY CHARGED ROTORCRAFT MIGHT ACT AS A SOURCE OF ELECTROMAGNETIC RADIATION. THESE ARE NARROW BAND ELF RADIATION PRODUCED BY CURRENTS INDUCED BY ROTOR ROTATION AND BROADBAND ELECTROMAGNETIC RADIATION FROM P STATIC. IN ORDER TO DETERMINE WHETHER OR NOT RADIATION DUE TO THESE MECHANISMS IS DETECTIBLE A COMBINATION OF NUMERICAL MODELLING TECHNIQUES IS ...

THE ESTIMATION OF THE COMPUTER CAPACITIES REQUIRED TO SUPPORT A MISSION ARE USUALLY THE SUBJECT OF MUCH DISCUSSION. ESTIMATES OF THE WORKLOAD AND OTHER PARAMETERS VARY GREATLY. THE REASON FOR THIS IS THAT MOST APPLICATIONS DO NOT FIT THE TRADITIONAL TIMING AND SIZING EFFORT. NONE OF THE THREE COMPONENTS (WORKLOAD, PERFORMANCE REQUIREMENTS AND ARCHITECTURE) IS USUALLY PRESENT. WE CONTEND THAT THE M ...

A STUDY OF THE EFFICIENCIES AND ENGINEERING TRADE-OFFS INTEGRATING REDUNDANT NUMBER SYSTEM WITH SYSTOLIC ARRAY PROCESSING ELEMENTS IN ORDER TO CAPTURE THE INHERENT FAULT TOLERANT PROPERTIES OF SIGNED DIGITS IS PROPOSED. USING SIGNED DIGITS REDUCES CARRY/BORROW DISTANCE TO A MINIMUM THUS REALIZING HIGHLY MODULARIZED AND COLUMNAR ARITHMETIC ENGINES. PROCESSING CELLS BECOME REGULAR WITH FEWER INTERCO ...

A RESEARCH EFFORT COMPLETED RECENTLY FOR THE AIR FORCE IDENTIFIED NEW TECHNOLOGIES FOR ANGULAR MOTION MEASUREMENT. TWO CONCEPTS WERE FOUND WHICH APPEAR TO OFFER POTENTIAL FOR AN EXCELLENT COMBINATION OF SMALL SIZE, WIDE DYNAMIC RANGE, WIDE BANDWIDTH AND EASE OF FABRICATION AND UTILIZATION. ONE DEVICE, CALLED A FLUID-FILLED BENDER BEAM, USES PIEZOCERAMICELEMENTS TO PRODUCE A SIGNAL PROPORTIONAL TO ...

ALL SURVIVABILITY/VULNERABILITY COMPUTER CODES, INCLUDING THOSE FOR PROJECTILES, LASERS, AND RADIATION EFFECTS, INVOLVE TRACING SAMPLE PATHS (CALLED SHOTLINES) THROUGH COMPUTERIZED GEOMETRY MODELS. FOR COMPLEX EQUIPMENT, HUNDREDS OF THOUSANDS OF SHOTLINES ARE ANALYZED TO DETERMINE ITS VULNERABILITY TO VARIOUS WEAPON EFFECTS. THUS, THE SHOTLINE-TRACING COMPUTER CODES STRONGLY INFLUENCE THE ACCURACY ...
